Predictive Mining from live mempool data — block lookahead +1/+2/+3 with hit-rate tracking
Bitcoin Knots Spam-Filter active
Clean Blocks
~95% spam removed
We filter Ordinals, Inscriptions and other non-financial payload at node level. That is why this mempool looks smaller than mempool.space (Bitcoin Core) — but every TX you see here is real money. Predictor and DATUM template only work with paying transactions.

Predictive Hit-Rate — how well do our predictions perform?
Comparison of our block +1/+2/+3 bucket predictions against actual blocks. Higher values = better Mempool predictive performance.

What-if — live threshold simulation
Move the sliders — the effect on historical TXs is shown live below. Only when you click on "Activate these thresholds" is the threshold actually pushed to the worker.

⚠️ No TX data available for simulation yet. The mempool streamer must first collect data. Sliders already work — hit counts will appear as soon as the worker runs.
Multi-block lookahead — pre-heated templates (block +1 / +2 / +3)
What the big pools also do: hold 3 block templates in memory in parallel, switch in <50 ms on tip change. Data flows 1:1 like on mempool.space — sorted by fee rate, with your threshold-hit markers.
